HIV decreases natural immunity of the body by destroying:

Options

A. Erythrocytes
B. Antibodies
C. T-lymphocytes
D. B-lymphocytes

Answer

**Step-by-Step Solution:**

1. **Understanding HIV**: HIV stands for Human Immunodeficiency Virus. It is a virus that attacks the immune system, specifically targeting certain types of white blood cells.

2. **Role of T-helper Cells**: The immune system relies on T-helper cells (a type of T-lymphocyte) to coordinate the immune response. These cells send signals to other immune cells, including B-cells, to produce antibodies that fight infections.

3. **Mechanism of HIV**: When HIV enters the body, it primarily infects and destroys T-helper cells. This process significantly impairs the immune system's ability to respond to infections.

4. **Consequences of T-helper Cell Destruction**: The destruction of T-helper cells leads to a weakened immune response. Without these cells, the body cannot effectively signal B-cells to produce antibodies, making it vulnerable to infections and diseases.

5. **Conclusion**: Therefore, HIV decreases natural immunity by destroying T-helper cells, which are crucial for the immune response.

**Final Answer**: HIV decreases natural immunity of the body by destroying T-helper cells.
